This keto coconut cake is made with the same basic ingredients as any almond flour cake. If you have baking ingredients like baking powder already on-hand then you are ready to make this coconut cake.
See the keto cake recipe card below for quantities, full instructions, and recipe notes.
- Almond flour - Definitely use finely ground flour rather than almond meal so that the cake turns out nice and soft.
- Baking powder - do not get confused with baking soda.
- Coconut flakes - Any kind of unsweetened shredded coconut will work, and toasted coconut will have a richer flavor.
- Granulated Sweetener - the most popular sugar replacements for your sweet tooth are erythritol, monk fruit, stevia, and allulose. Other sugar alcohols such as xylitol are also used often in keto recipes. All have zero or low net carbs and will not impact blood sugar.
- Psyllium Husk
- Butter - Use salted butter, or unsalted butter and add a pinch of salt.
- Eggs - fresh eggs
- Lemons - You will use the juice and zest from two lemons.
Lemon Cream Cheese Yoghurt Icing
To make coconut frosting, see the variations below.
- Cream Cheese - Use full-fat cream cheese and soften it first.
- Unsweetened Yoghurt - Make sure it is unflavored and unsweetened
- Lemon Zest
- Powdered sweetener - powdered erythritol makes for a fine and smooth creamy frosting rather than using granulated sweetener.
This keto coconut cake is a very simple recipe.
Start out by mixing the dry ingredients together - ground almonds, coconut, baking powder, sweetener, and psyllium husk in a mixing bowl.
Then, add the wet ingredients - melted butter into the middle of the dry ingredients and mix them together gently. Add the eggs and keep mixing.
Add the lemon juice and lemon zest.
Line the baking tin with baking parchment paper to ensure it lifts out easily.
Pour the coconut cake batter into the greased and lined ring pan.
Keep baking the gluten-free coconut cake until a toothpick inserted into the middle comes out clean.
Cool the cake pan completely on a cooling rack before you add the creamy buttercream frosting.
Your keto coconut cake can be stored with or without the coconut frosting.
You can store a whole cake or individual slices.
Store leftover cake in an airtight container and keep it in the refrigerator.
Leftover slices of frosted cake will stay fresh for about 5 days. Remember to keep it covered so that the moist keto coconut cake does not dry out.
Store individual slices of cake in an airtight container or a ziplock bag in the freezer for up to 3 months. Remove one slice of cake as you need it, and leave it covered on the kitchen bench at room temperature for 2 hours.
You can serve your keto coconut cake in so many ways.
- Sweetened whipped cream - whip heavy cream and sweetener together until stiff peaks form.
- Lemon yogurt frosting - see the recipe card below.
- Vanilla cream cheese frosting - the versatile keto cream cheese frosting can be made in 7 flavors.
- Sugar-free coconut frosting - add coconut stevia drops or coconut extract to your frosting instead of vanilla extract.
- Toasted coconut - sprinkle over your frosting around the edges for an extra hit of coconut flavor.
- Whipped coconut cream -

To make this keto coconut cake, I used a ring tin, or a cake pan with a hollow middle. Some people call this a bundt pan.
To prevent the cake batter from sticking, I suggest lining your cake pan with baking parchment paper.
Since you need to mix the ingredients gently, use a wooden spoon to mix the batter of this delicious cake.
To make the frosting for this keto cake, use a stand mixer or an electric mixer of some kind.
Here are some questions people often ask about how to make keto coconut cake. If you don't see your question in this list, please leave it in the comments.
Yes, you can freeze this cake. I prefer to freeze the cake before I add the frosting or glaze because it is easier to wrap in aluminum foil.
This depends on the ingredients you use, but all the recipes on Ditch The Carbs are healthy. They will not cause crazy fluctuations in your blood sugar and are awesome recipes when you are craving something sweet.
Even better, my keto desserts are made with high-protein and healthy-fat ingredients.
I used almond flour instead of coconut flour in this cake. Coconut flour absorbs more liquid when you bake with it, so you will have to adjust how much liquid you use. I do not suggest trying to replace the almond flour with coconut flour. It won't work. (Here's why)
I called this a coconut cake because I used lots of shredded coconut, not because I used coconut flour in the cake batter.
No, you do not need to use coconut milk or canned coconut milk in this sugar-free coconut cake recipe. Since I did not use coconut flour, you don't need as many wet ingredients in the batter.
You can decorate your coconut cake with whipped heavy cream or whipped coconut cream, with sweetener and coconut extract for an extra coconut flavor. Gently spread the whipped frosting on the top and the sides of your coconut cake then sprinkle with coconut flakes.
No, you can only whip coconut cream.
Most sugar alcohols are not absorbed so are not included in the carb count of keto recipes and healthy recipes.
